Meet our Essentials Collection, made with our proprietary natural fiber triblend yarn plus the ideal amount of spandex for stay-put comfort all day long. With the power of supersoft (never itchy) alpaca fiber built right in, this breathable mid-rise women's underwear keeps things dry and odorless. And with the ability to stretch but always keep its shape, sustainably made brief is unlike any you’ve worn before. Let these natural fibers do the work for you, and you'll forget they're even there.
